Abstract
Plant communities that included Astragalus sericeocanus were studied. The data on ontogenetic structure, quantity of cenopopulations and seed productivity of individuals were given. It was also revealed that the habitats on the northern shore of Lake Baikal are characterized by high phytocoenotic diversity with codominating and dominating of A. sericeocanus . The state of cenopopulations and parameters of seed productivity showed that northern habitats have considerably favourable climatic conditions which are optimal for the growth of the studied species.
